Background: Life satisfaction is a key component of subjective well-being in later life and may be associated with psychological, economic, family, functional, and food-related factors. Objective: This study aimed to identify factors associated with life satisfaction among older adults, considering sociodemographic characteristics, food insecurity, physical activity, and psychological factors. Methods: A quantitative, observational, analytical, cross-sectional study was conducted with 200 noninstitutionalized older adults from Sogamoso, Colombia. Self-report instruments assessed life satisfaction, food insecurity, physical activity, depression, anxiety, and perceived stress. Data were analyzed using descriptive statistics, group comparison tests, Pearson correlations, and multiple linear regression. Results: Higher perceived stress (B = −0.762, p < 0.001), perceived insufficient income (B = −3.380, p < 0.001), self-employment (B = −2.153, p = 0.009), other sources of income (B = −2.569, p = 0.017), and technical education (B = −4.744, p = 0.003) were associated with lower life satisfaction. Conversely, combined engagement in strength and flexibility exercises (B = 3.203, p < 0.001), having two children (B = 3.498, p = 0.002), and having three or more children (B = 2.618, p = 0.008) were associated with higher life satisfaction. Primary education was not significantly associated with life satisfaction after adjustment (p = 0.093). Food insecurity was associated with life satisfaction in the bivariate analysis but did not remain statistically significant in the adjusted model. The regression model explained 48.7% of the variance in life satisfaction (R² = 0.487; adjusted R² = 0.457). Conclusions: Life satisfaction among older adults was associated with psychological, economic, family, and functional factors. The findings highlight the relevance of perceived stress, economic security, functional physical activity, and family resources when addressing subjective well-being in later life.

Background/Objectives: Sleep duration and physical activity are key behavioral components in the development of healthy lifestyles during adolescence. In Peru, a considerable proportion of school students do not meet recommended levels of physical activity and may also experience insufficient sleep, which could negatively affect their eating habits. This study aimed to analyze the association between sleep duration, physical activity level, and healthy eating habits among Peruvian secondary school students. Methods: An observational, analytical, cross-sectional study was conducted among 275 secondary school students aged 12 to 17 years. Sleep duration, physical activity, and eating habits were assessed using validated questionnaires. Associations were analyzed using Pearson’s chi-square test and multivariable binary logistic regression. Results: Students who slept 7 h had higher odds of having healthy eating habits compared with those who slept 6 h or less (aOR = 2.525; 95% CI: 1.181–5.536; p = 0.018). In addition, students with low levels of physical activity showed lower odds of having healthy eating habits compared with those with high levels of physical activity (aOR = 0.097; 95% CI: 0.005–0.564; p = 0.032). Conclusions: Sleep duration and physical activity were associated with healthy eating habits among Peruvian secondary school students. These findings support the importance of promoting integrated school-based strategies that jointly address sleep, physical activity, and nutrition during adolescence.

Introduction: Work-related musculoskeletal disorders are common among nursing staff and may affect functionality, psychological well-being, and work performance. Brief, culturally adapted, and psychometrically sound instruments are needed to characterize musculoskeletal risk in occupational settings. This study aimed to translate, culturally adapt, and examine the structural validity and internal reliability of the abbreviated version of the Örebro Musculoskeletal Screening Questionnaire in Peruvian nurses with musculoskeletal symptoms. Methods: An instrumental, cross-sectional study was conducted with a sample of 170 Peruvian nurses. The Spanish-adapted version of the ÖMSQ-12S was administered. Descriptive statistics, corrected item-total correlations, confirmatory factor analysis using the robust maximum likelihood estimator, internal reliability through Cronbach’s alpha and composite reliability, convergent validity through average variance extracted, and discriminant validity using the Fornell–Larcker criterion were analyzed. Results: The original three-dimensional 12-item model showed inadequate fit: χ²(51) = 276.301, CFI = 0.713, TLI = 0.628, RMSEA = 0.161, and SRMR = 0.190. Due to low and divergent factor loadings, a refined 11-item, four-factor solution was evaluated: functionality/satisfaction, fear-avoidance, psychological aspects, and characteristics of the musculoskeletal problem. This model showed better fit: χ²(37) = 58.190, CFI = 0.971, TLI = 0.957, RMSEA = 0.058, and SRMR = 0.039. Reliability was adequate across all factors (α = 0.773–0.893; CR = 0.779–0.895). Convergent validity was acceptable in most dimensions, although discriminant validity was limited between psychological aspects and characteristics of the musculoskeletal problem. Conclusions: The ÖMSQ-11S showed preliminary evidence of structural validity and internal reliability in Peruvian nurses with musculoskeletal symptoms. However, its use as a predictive tool or universal occupational screening instrument requires further studies with longitudinal designs, more heterogeneous samples, and external clinical or occupational criteria.

Background: Writing self-efficacy is a central construct in educational research, grounded in Bandura’s social cognitive theory. However, most available instruments have been developed in Western and urban contexts, which limits their applicability to indigenous bilingual populations, such as Quechua-speaking students in Peru. The absence of validated scales in these contexts hinders the accurate assessment of writing self-efficacy and the implementation of educational strategies tailored to their linguistic and cultural needs. Objective: This study aimed to adapt and validate the Writing Self-Efficacy Scale (QEWSE) for Quechua-speaking students in basic education in Peru, ensuring its structural validity and reliability. Methods: An instrumental study was conducted with a sample of 265 secondary school students (50.6% female, 49.4% male), using convenience sampling. Confirmatory factor analysis (CFA) was applied to evaluate the structure of the instrument. Reliability was assessed using Cronbach’s alpha and McDonald’s omega coefficients. Results: The four first-order factor model (Ideation, Skills, Usage, and Self-Regulation) showed adequate fit indices (CFI = 0.92; TLI = 0.91; RMSEA = 0.05 [90% CI: 0.05–0.06]; SRMR = 0.05). However, the high inter-factor correlations (≥0.85) suggest the relevance of a second-order model, which demonstrated a reasonable fit (CFI = 0.92; TLI = 0.91; RMSEA = 0.06; SRMR = 0.05), supporting the interpretation of writing self-efficacy as a global construct. The scale showed high reliability across all factors (α and ω ranged from 0.74 to 0.90). Conclusions: The QEWS-S demonstrates strong psychometric properties for assessing writing self-efficacy among Quechua-speaking students. The hierarchical second-order model offers a more accurate theoretical and empirical representation, allowing for the reporting of an overall self-efficacy score while also providing specific scores for each dimension. These results support its use in bilingual and culturally diverse contexts and lay the groundwork for future research aimed at further examining discriminant validity and developing pedagogical interventions focused on strengthening students’ confidence and writing skills.

Background: Team viability, understood as the ability to adapt and collaborate effectively over time, is a key concept in organizational literature. In Peru, where changes are constant, culturally adapted tools are needed for its measurement. Objective: To translate and validate a team viability scale for Peruvian workers. Methods: An instrumental design was used with 290 public sector employees (M = 34.61; SD = 9.2). The translation followed a cultural adaptation process, and validity was assessed through descriptive, correlational, and confirmatory factor analysis. Results: Confirmatory factor analysis supported a unidimensional structure with excellent fit indices (CFI and TLI > 0.99, RMSEA and SRMR < 0.01). The scale showed high invariance across gender and good internal consistency (α = 0.90). Conclusions: The validated scale is a reliable tool for measuring team viability in Peru. Its implementation can enhance human resource management and improve collaboration in the public sector.

AI has revolutionized the workplace, significantly impacting the nursing profession. Attitudes toward AI, defined as workers’ perceptions and beliefs about its utility and effectiveness, are critical for its adoption and efficient use in clinical settings. Factors such as age, marital status, and education level may influence this relationship, affecting job performance. This study examines the influence of attitude toward AI on job performance with AI among Peruvian nurses, while also assessing how sociodemographic characteristics moderate this relationship. A descriptive cross-sectional design was used with a sample of 249 Peruvian nurses aged 24 to 53 years (M = 35.58, SD = 8.3). Data were collected using two validated scales: the Brief Artificial Intelligence Job Performance Scale (BAIJPS) and the Attitude toward Artificial Intelligence Scale (AIAS-4). Descriptive statistics, Pearson correlations, and multiple linear regression were applied. A significant positive correlation was found between attitude toward AI and job performance with AI (r = 0.43, p < 0.01). Age (β = -0.177, p < 0.05), divorced marital status (β = -8.144, p < 0.01), and having a bachelor’s degree (β = -3.016, p < 0.05) were negatively associated with job performance, while being from the Selva region had a positive effect (β = 4.182, p < 0.05). A favorable attitude toward AI positively influences nurses’ job performance, highlighting the need for interventions that enhance AI perception. Age, marital status, and education moderate this relationship, suggesting AI adoption strategies should be tailored to different demographic groups.

Background: The advancement of artificial intelligence (AI) in education has transformed the way students interact with technological tools, creating new challenges related to self-efficacy, anxiety, and AI dependence. Self-efficacy refers to one's confidence in their ability to use AI, while AI-related anxiety pertains to the fear or concern when interacting with these systems. These variables can influence technological dependence, affecting academic performance and emotional well-being. Objective: This study aims to examine the influence of self-efficacy in AI use and anxiety toward AI on AI dependence among Peruvian university students. Methods: A descriptive cross-sectional study was conducted with 528 Peruvian university students aged 18 to 37 years (M = 19.00, SD = 3.84). Scales were used to measure AI self-efficacy, anxiety toward AI, and AI dependence. Correlation and multiple regression analyses were applied to identify predictors of technological dependence. Results: The results showed that AI self-efficacy was positively correlated with AI anxiety (r = 0.43, p < .01) and AI dependence (r = 0.61, p < .01). Anxiety also significantly correlated with AI dependence (r = 0.71, p < .01). Multiple regression analysis revealed that both AI anxiety (β = 1.131, p < .001) and AI self-efficacy (β = 0.610, p < .001) predicted AI dependence. Additionally, business administration students exhibited greater dependence compared to students from other fields (β = 1.025, p < .05). Conclusions: Students with higher self-efficacy in AI use tend to utilize AI more frequently but also experience greater anxiety and dependence on AI. Educational interventions should focus on reducing AI-related anxiety to prevent excessive dependence, especially among students.

Background Transformational leadership has been identified as an essential component for success and innovation within the public sector, especially in the digital age and in the face of global challenges. This form of leadership, which seeks to change and inspire people, has been shown to be crucial for improving organizational performance and the quality of public services. However, the application of these principles in Peru faces specific challenges, and there is a notable lack of empirical research on this phenomenon in the Peruvian public sector, particularly in the evaluation of the tools used for its measurement. Objective This study aimed to examine the psychometric properties of the Global Transformational Leadership (GTL) scale in a sample of Peruvian public servants. Methods An instrumental research design was adopted, using non-probabilistic sampling. The sample included 290 Peruvian public servants (M = 34.61, SD = 9.2), with an analysis that encompassed confirmatory factor analysis (CFA) and reliability estimates. Results Descriptive analysis results indicated a high tendency to respond positively on the scale. The CFA confirmed the proposed unidimensional structure of the scale, with acceptable fit according to various indices (χ2 = 39.130, CFI = 0.97, TLI = 0.95, RMSEA = 0.08, SRMR = 0.03), and all factor loadings were significant and greater than 0.50, indicating a strong association with the transformational leadership dimension and exceptionally high internal consistency (α = 0.94). Conclusions The study confirmed that the GTL transformational leadership scale is a psychometrically robust tool and applicable to the Peruvian context. The unidimensional structure and high reliability of the scale suggest that it is suitable for measuring transformational leadership among public servants in Peru.

Introduction: work performance in nursing is crucial for the effectiveness of health services and the quality of patient care. Factors affecting this performance include work motivation, organizational culture, institutional support, and working conditions. The need for accurate tools to measure work performance in specific contexts, such as nursing in Peru, is imperative, especially given the increased demands and pressures brought about by the COVID-19 pandemic. Objective: this study aims to adapt and validate a Short Version of the Self-Assessment Work Performance Scale for Peruvian nursing staff, ensuring its relevance and psychometric accuracy in this specific context. Method: an instrumental design was used with convenience sampling, selecting 409 Peruvian nurses (M=20,22, SD=2,6). The scale, composed of 10 items, was adapted to Spanish and evaluated through confirmatory factor analysis. Reliability measures such as Cronbach's alpha and McDonald's omega were employed, along with invariance analysis to ensure the scale's consistency across sexes. Results: the factor structure confirmed the construct validity of the scale with a good fit in the unifactorial models (χ² = 139,820, df = 35, p < ,001, CFI = 0,94, TLI = 0,93, RMSEA = 0,07, SRMR = 0,03). Reliability was high, with Cronbach's alpha and McDonald's omega of 0,92 for the general model. The scale demonstrated full measurement invariance across sexes, reinforcing its applicability in gender-divided populations. Conclusions: the scale is a valid and reliable tool for assessing work performance in nursing staff in Peru. Its ability to adequately reflect the specific conditions and challenges of this professional group ensures its utility in the continuous improvement of health service quality and effective management of nursing staff in diverse and demanding contexts
